RGBW and Color Tuning

White color tuning refers to the ability of a light fixture to adjust its color temperature to the color temperature preference (2700K-5500K) of the occupant anytime after the installation.

RGB+W and Full-Color Tuning

Full-color tuning refers to the same ability but additionally to produce a color output anywhere within the visible color spectrum, and is most commonly accomplished through the mixing of several base-color LEDs, most commonly RGB (Red, Green, Blue) and RGBW (Red, Green, Blue, White).
